Digital Bazaar's open source vc-js library will support proof sets and chains (as specified in the Data Integrity spec by the VCWG) in production. There is strong customer pull for proof sets. There is not strong customer pull for proof chains, but given that we have the opportunity to define a global standard for doing that AND because there are use cases like notarization that are important, we plan to add full support for that as well. Regarding the concept of multi-signature, I am a bit concerned that people are talking past each other as there are a number of categories there and it's possible that not everyone is talking about the same categories of multisig. There are at least these categories: * Using multiple proofs to perform set-based multi-signature. * Using multiple proofs to perform chain-based multi-signature. * Using multiple proofs to perform multi-level/enveloped multi-signature. * Using a single proof to perform set-based multi-signature. * Using a single proof to perform chain-based multi-signature. * Using a single proof to perform M of N threshold multi-signature. * Using a single proof to perform privacy-preserving M of N threshold multi-signature. So, when you say "multi-signature" -- which one of these things are you talking about? -- manu -- Manu Sporny - https://www.linkedin.com/in/manusporny/ Founder/CEO - Digital Bazaar, Inc.
